Lower Northern Thailand can be described as the cradle of Siam. Located in the northernmost part of the Chao Phraya Basin, the Kingdom of Sukhothai was the first major Thai realm and the earliest direct predecessor of the modern state of Thailand. It climaxed in the early-13th century AD and is viewed as a first zenith of Thai (especially Buddhist) art. Buddha statues from this era belong to the most elegant works in the history of Siamese art. The Thai script was developed in Sukhothai as well as other aspects that are now considered typical for Thai culture. The Historical Parks of Sukhothai, Si Satchanalai and Kamphaeng Phet are evidences of this era. However, soon after the death of its paramount king Ramkhamhaeng, the Kingdom of Sukhothai declined.
In the mid-14th century, the capital was moved to Phitsanulok, where several Buddhist temples were erected or enhanced during that time. After 1438, Lower Northern Thailand was merged into the Central-Thai Kingdom of Ayutthaya, but maintained some regional autonomy and cultural distinctions, with Phitsanulok serving as a "second capital" of the Ayutthayan Empire and nobles from Lower Northern Thailand often playing the role of king-makers. Efforts of the Kingdom of Lan Na (centered around Chiang Mai) to conquer Lower Northern Thailand remained unsuccessful. The 16th-century warrior-king Naresuan, one of the most famous rulers in Thai history, was born and raised in Phitsanulok.
In terms of cultural traditions, dialect and cuisine, Lower Northern Thailand is closer to the Central region than to (upper) Northern Thailand.
The closest international airports are in Bangkok (BKK or DMK). The region has two minor airports, Phitsanulok (PHS) and Sukhothai (THS) that are only served by domestic flights.
Lower Northern Thailand lies on the State Railway of Thailand's (SRT) Northern line, about halfway between Bangkok and Chiang Mai, with notable stops in Nakhon Sawan, Phichit, Phitsanulok, and Uttaradit.
Most provinces in Lower Northern Thailand are best to reach by intercity bus. All provincial capitals and some other towns have direct bus links with Bangkok. Some places are also directly accessible from Chiang Mai, Chiang Rai or Khon Kaen.
If your destinations are not on the Northern railway line (see above), busses are the usual means of choice to get from one province to another. For short distances or remote places, there are Songthaeos (converted pickups with passenger benches on the bed).

The cuisine of Lower Northern Thailand is similar to the one of Central Thailand, you will get all classical Thai dishes. As most cities of this region are located along a river, a lot of freshwater fish is served, but also chicken, pork and vegetables. Do not expect typical Northern Thai cuisine (i.e. the one of Chiang Mai, Chiang Rai etc).
